   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0457 AM CDT TUE AUG 12 2003
   
   VALID 121200Z - 131200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR ERN ID/CNTRL MT...
   ...CRITICAL FIRE WEATHER AREA FOR CNTRL NV...
   
   ...SYNOPSIS...
   WEATHER PATTERN WILL BE SIMILAR TO MONDAY...WITH BROAD MODERATE SWLY
   FLOW ACROSS THE PACIFIC NORTHWEST/GREAT BASIN. EARLY MORNING WATER
   VAPOR IMAGERY SHOWS A SHORTWAVE TROUGH MOVING ACROSS CNTRL WA/ORE AT
   12/0900Z...WITH MID/UPPER LEVEL MOISTURE PLUME MOVING NEWD ACROSS
   THE GREAT BASIN AND NRN ROCKIES. SFC FEATURES OF INTEREST WILL BE A
   STATIONARY FRONT ACROSS MT WITH A LEE SIDE TROUGH EXTENDING ALONG
   THE ERN HIGH PLAINS OF WY/CO. GUSTY SFC WINDS AND DRY LIGHTNING WILL
   BE THE MAIN FIRE WEATHER THREATS TODAY.
   
   ...CRITICAL FIRE WEATHER AREA 1 - ERN ID/CNTRL MT...
   
   PRIMARY CONDITIONS: SUSTAINED SFC WINDS 15-25 MPH WITH HIGHER GUSTS
   / MINIMUM RH VALUES BELOW 20 PERCENT / MAX TEMPS IN THE 80S/90S /
   DRY LIGHTNING / EXTREME FIRE DANGER CLASS OBSERVATIONS...
   
   VISIBLE SATELLITE IMAGERY FROM MONDAY INDICATED MANY SMOKE PLUMES
   ACROSS ID/WRN MT AND THIS IS WHERE MANY LARGE FIRES CONTINUE. EARLY
   MORNING VWP DATA FROM BOISE ID SHOWS MID LEVEL 50 KT WINDS. SFC
   WINDS ACROSS THE OUTLOOK AREA WILL NOT BE AS STRONG AS
   YESTERDAY...BUT THERE WILL STILL BE WIDESPREAD GUSTY WINDS. MINIMUM
   RH VALUES WILL FALL BELOW 20 PERCENT WITH EXTREMELY DRY FUELS PER
   LATEST FIRE DANGER CLASS OBSERVATIONS. DRY LIGHTNING IS A CONCERN
   WITH TSTMS...WITH BEST INSTABILITY ACROSS CNTRL/ERN MT. BEST
   POTENTIAL FOR DRY LIGHTNING WILL BE ACROSS THE BITTEROOT RANGE AND
   THE SWRN MTS OF MT. HOWEVER...ALL TSTMS MAY CONTAIN SOME DRY
   LIGHTNING...AND WILL POSE A HAZARD GIVEN THE CRITICAL FIRE WEATHER
   CONDITIONS.
   
   ...CRITICAL FIRE WEATHER AREA 2 - CNTRL NV...
   
   PRIMARY CONDITIONS: SUSTAINED SFC WINDS 15-25 MPH WITH HIGHER GUSTS
   / MINIMUM RH VALUES BELOW 10 PERCENT / MAX TEMPS IN THE 90S /
   EXTREME FIRE DANGER CLASS OBSERVATIONS...
   
   VERY STEEP LAPSE RATES WILL ALLOW FOR WELL MIXED BOUNDARY LAYER
   CONDITIONS TODAY. WINDS AT THE TOP OF THE BOUNDARY LAYER WILL
   GENERALLY BE IN THE 25-35 KT RANGE...WHICH WILL RESULT IN SUSTAINED
   SFC WINDS NEAR 20 MPH...WITH LOCALLY HIGHER GUSTS. IN
   ADDITION...MINIMUM RH VALUES WILL FALL BELOW 10 PERCENT...WITH TEMPS
   IN THE 90S. ISOLATED DRY TSTMS MAY BE POSSIBLE ACROSS EXTREME NERN
   NV...BUT FARTHER WEST CONDITIONS SHOULD BE TOO DRY FOR ANY
   THUNDERSTORMS TO DEVELOP. TSTMS ARE LIKELY ACROSS UT/WY...AND THE
   FOUR CORNERS REGION...AND SOME OF THESE MAY CONTAIN DRY LIGHTNING.

   TRIGGERING SOME TSTMS. MEANWHILE...HIGH PRESSURE WILL BUILD EWD
   ACROSS THE NRN PLAINS...WITH MODERATE SW/WLY MID LEVEL FLOW
   PERSISTING ACROSS THE GREAT BASIN/NRN ROCKIES. AT THE SFC...A
   BOUNDARY WILL EXTEND ACROSS SRN MT WITH A SFC LOW LOCATED IN SERN
